Matsya Purana — Description of the Daitya–Dānava War Preparations and Maya’s Divine Chariots
मयस्तु काञ्चनमयं त्रिनल्वायतमक्षयम् चतुश्चक्रं सुविपुलं सुकल्पितमहायुगम् //
mayastu kāñcanamayaṃ trinalvāyatamakṣayam catuścakraṃ suvipulaṃ sukalpitamahāyugam //
But Maya (the master architect) fashioned an imperishable structure made of gold—measuring three nalvas in length—very spacious, fitted with four wheels, and excellently designed to endure for a great age (mahāyuga).
This verse does not describe pralaya directly; instead it emphasizes “akṣaya” (imperishable) construction—suggesting a divine standard of durability meant to last across vast cosmic timescales (mahāyuga).
By highlighting precise measurement and sound construction (sukalpita), it supports the Matsya Purana’s broader ethic that rulers and householders should sponsor well-planned, enduring public works—built with correct proportions and expert craftsmanship.
It encodes Vastu-style ideals: correct dimensional specification (tri-nalva-āyatam), structural excellence (sukalpita), and longevity (akṣaya). The “four-wheeled” detail points to a ritually and symbolically complete vehicle/structure (ratha/vimāna) designed by an expert architect (Maya).
